Ha Ha.... Yea man, we live we learn, making everything much stronger now... Yea Mr Musk doesn't give up easy!!! neither do I... The Force is with U my friend!
It’s estimated by his records that Thomas Edison failed 2774 times at creating the lightbulb before he succeeded. It’s called R and D. You’ve discovered what won’t work now. And based on your discovery you’ve got a better point to start from to succeed. The boat looks great. It’s got to be so nice to have it in the water and shaking down the systems to see what needs more development. So happy for you two!
Thank's for raising Edison as an example... He never failed John, cos he never quit! That's the difference between failure and conclusions drawn by set backs... Once a person gives up, he has failed, if he continues he has a greater chances for success. exactly what you said, but it's a mind set. It's about believing in ones self, it's about not fearing set backs, not thinking about what others will say.... I have many friends with great dreams that are afraid to take the first step to make them come true.... Since I grew up I just say "wow, cool.... Amazing...." I know nothing's gonna happen.... Living in a heard has it's downsides I suppose.... Keep Shunting Man! How's the Surf??? By d Way....
Welcome to the club! I guess that shaft was a little skinny. Hmm, though I notice it compressed there... probably where it goes through the support right? like it pressed against the guide and started to flatten it, and then when that happens it becomes narrower and a weak point. What if you just poured some hardened epoxy down there so that section is solid all the way through and can't compress? But anyway, yeah a multihull seems to go from very little force on the rudder when smooth sailing to really massively more force! but the most is when you are surfing down a wave, trying to hold it straight! you might normally be sailing along at 7knots, then surfing a wave... i've seen (momentarily) 15 knots on my gps while surfing. aerodynamic/hydrodynamic forces are proportional to the square of the velocity, so doubling the speed quadruples the force. Hmm so if it bent going 7 knots, I think you need to make it 8 times stronger so it will survive 15
Yea, messy stuff.... you probably got the figures right mate.... Anyway, it was a balanced rudder, made so I could get more area for a bigger sail. I hated it, zero feel!!! Balanced rudders suck!!! their leading edge bites and they fly over. So that got cut off! so less area now, less biting and spinning onto 90 degrees now.... I will push it up about 10 cm reducing leverage, giving the bad water a harder time bending it again. Finally I'm going to weld another pipe inside both my rudders with a thicker wall, see how that works.... Then maybe think about the metal frame at the bottom connected to the hull... I may be adding much bigger backing plates inside the hull.... Anyway, boat sails great for first time, very pleased. Keep Shunting, bro BSY
@@BalkanShipyards oh interesting! actually that happened to me with the latest iteration of my self steering (which isn't a video yet, but soon) I wanted a more powerful servo fin so I gave it some balance... it worked at small angles, but at big angles it jammed on and then went hard to the side. I disagree balanced rudders are bad... too much balance is bad. I'm gonna just cut off some of the balance. Enough balance to make a lighter helm, but enough trail so that the flow will turn it back to center on it's own and you'll have some feel. Definitely eager to see Crystal Clear sailing! Winter is starting here...
Hello, I'm sorry to hear about your rudder problem. What was the shaft made of? I'm building a rudder of about the same size. Hope you can replace it soon. My rudder shaft is made of solid fiberglass 20 mm diameter. Have a good trip. Fjordproa.👍
I will fix it, by putting a thicker pipe inside and welding it, I will do the same to the other one too. It was a Stainless steel pipe 25x1.5mm the wall was too thin... Keep Shunting, Balkan Shipyards
Can you fix it where you are or do you have to go home? That engine seems to be working well. The boat is moving nicely with it. Just keep on shunting.....
I have other thigs to do too, so just drove 300 km home, Balkan Km, takes 4 to 5 hours..., cut off the balanced leading edge and glassed them up, maybe tomorrow evening primer... Welded them up with 22x3 mm pipes inside... I just want to sail properly and I may make new ones. Keep Shunting pal
Looks like something you can fix, no one was injured and the boat's not full of water so everything's still good, so next video is the rudder upgrade video?
Correct! just another stepping stone on the endless journey to perfection... well they are done, just came in, worked till midnight in the dojo...... So yea could shoot a shorty sowing what I did. All d best Dave
Sounds like you changed then name of the proa... This is so cool man.. Super amazing.. Happy watching the vid. For sure a great boat... Just a few thoughts I have are, ama and Vaka have pronounced rocker and rightfully so to work the lumpy seas... on anole I made the ama with much less rocker than the main hull. I noticed when Lucky Pigeon was backwinded with an ama to leeward that had more pronounced rocker than the main hull, the boat tracked so perfect, it really accelerated and went super straight through the chop. So, my conclusion was that the leeward hull should have more rocker than the windward hull because L Pigeon main hull had heavy rocker but the ama was shorter with eleven more rocker. In your case that would mean a flatter ama and main hull as is. Thought I would share because when I saw your ama in the shop in another vid I remember thinking how much curve it had like a banana, but you know not even that much, but definitely rocker in there. I haven't finished Anole yet, but am super curious about how a flatter ama and a more curved main hull will be. Also if you made a Harry Proa out of this one with a fat ama that was flat and longer... oh man I think you could sail around the world. Even put your original Crystal Clear hull on windward... you would have sooo much displacement and deck area. These home build multi-hulls are infinite in possibility, it just rattles my brain , but I love it. Anyway, thanks for the inspirations always and sharing the stuff. Its great.
Interesting thoughts Zack, yet gone down this path too long and far for radical changes... Harry Proas are weird and too much weight to windward changes from Pacific to Atlantic or what ever else has been invented.... (there's another type they call Indian Proa which is some weird concept that I cant remember...) So yea rocker of ama VS Vaka that I will look into, the best would be making small models ant testing them. But I'm going to reinforce a rudder! Hope I get it right this time, please read the reply I wrote to Dominic Tarr, I explained why it probably bent... I hope I get it right without going overboard in weight..... Keep Shunting bro, How's yor cat???
@@BalkanShipyards Catamaran launch in 2 to 3 weeks. Been working the dock to save a little money for some down days. Looking forward to having a place to chill on the water this summer.
I shuved a thick pipe inside it and welded it up, put the same pipe into the other one. Just need to test this boat, then I can make new ones, maybe....
Just like SpaceX, hope you got a lot of data for your next attempt. May the force be with you!

Easy fix.
Yea Peter, I will cut it and weld a thick pipe inside it, this was a 25x1.5mm SS pipe... Thin wall....
